I have my chickens on a nipple waterer that it fixed to the bottom of an air tight 2 gallon bucket. (I change the water before the 2 gallons is gone) but every now and then i will give them water in a pan to drink for the day. They have went weeks before with just the bucket waterers. But when i put water in the pan they will get excited and drink alot of it. Do they just like the fact that im out there giving them water in the pan or are they not getting enough from the buckets? I'd like to know if anybody else is watering there chickens strictly on the nipples. Thanks for reading!
